Can I use WHMCS plugin instead of Pro Sites plugin?

Hello Everyone!!

I need a plugin to sell both a website and other products. So, I think it is best to use the WHMCS plugin instead of the Pro Sites plugin?

In other words, I think that If I was only selling websites, then the Pro Sites plugin would be the best plugin, but since I will sell other products, the WHMCS plug in is a better choice.

Am I right to assume that I can do the client management with this plugin to sell websites and other products?

Thanks for your help!!
